Propagation

Seed - we have no information on this species but suggest sowing the seed as soon as it is ripe in a cold frame in the autumn. Stored seed should be sown in the early spring. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.

Division in the dormant season[5]. Basal cuttings in late spring. Harvest the shoots with plenty of underground stem when they are about 8 - 10cm above the ground. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer. Cuttings from the axils of larger leaves in early summer[5].

Root cuttings in the winter[6].
